Sex Pheromone of the Queen Butterfly: Biology

Science, 1969
Males of the queen butterfly Danaus gilippus berenice , deprived of the two extrusible brushlike "hairpencils" at the rear of their abdomen, are capable of courting females but incapable of seducing them. In normal courtship, an aphrodisiac secretion associated with the hairpencils is transferred by way of tiny ...

Sex Pheromone of the Queen Butterfly: Chemistry

Science, 1969
Two major components in the "hairpencil" secretion of the male of the queen butterfly ( Danaus gilippus berenice ) have been identified. One, a crystalline ketone (2,3-dihydro-7-methyl-1 H -pyrrolizin-1-one), is known from another danaid butterfly. The other, a viscous terpenoid alcohol (

Olfaction in the Florida Queen butterfly: Honey odour receptors

Journal of Insect Physiology, 1970
Abstract In an investigation of the role of olfaction in the life of the Florida Queen butterfly it has been found that honey odour can elicit proboscis extension. Selective blocking of antennal receptor types shows that only the short, thinwalled pegs are necessary for this response and only 5 to 10 per cent need be exposed for detection of honey ...

A behavioural analysis of the courtship pheromone receptors of the Queen butterfly, Danaus gilippus berenice

Journal of Insect Physiology, 1969
Abstract The chemo-stimulatory role of the male hair-pencils in the courtship behaviour of the Queen butterfly has been quantified experimentally in the natural habitat. Approximately 600 individuals were studied. Courtship success is substantially reduced either by removal of the male hair-pencils or by blocking the chemoreceptors on the female ...

An evolutionary-ecological model of the evolution of migratory behavior in the Monarch Butterfly, and its absence in the Queen Butterfly

Acta Biotheoretica, 1982
This paper presents a model that generates testable hypotheses concerning the evolution of long-range migratory behavior in the Monarch Butterfly,Danaus plexippus and the general absence of such behavior in a related form, the Queen,D. gilippus (Lepidoptera: Nymphalidae: Danainae).
